disable excessive (all) debug output in gui agent and guid

[marmarek]

Reported by joanna on 3 Oct 2011 13:02 UTC
When using with some programs that often refresh the window bitmaps (e.g. bochs) the amount of debug output printed by gui agent is huge and affects cpu performance significantly.

Besides, it's a usual practice to not output debug info, unless started with some option. So, I think we should implement a '--debug' switch for gui agent and gui daemon.

While at it, we should also rename the logs created by guid to something like guid.X.log (currently it is qubes.X.log).

In pre3 there is still plenty of stuff logged to /var/log/qubes/gui_agent.log -- those should be off by default. Same for Dom0 -- still too much stuff as for the production mode, please disable those by default.

Then bugreports will be almost useless.
What specific message do you thing is unneeded for production mode?

I think that logging of events that are more fine grained that window creation/destroy/manipulation should be disabled. So, events such as key-presses or mouse events, or pixmap updates, etc. So, generally, as far as I don't create, resize, etc, windows, there should not be (almost) anything logged. Currently gui_agents logs lots of stuff, such as move events, which makes the logs very huge BTW.

Mouse movement events are still being logged, which makes the gui agent log files to be several MB is size, and (I guess) also contribute to increased CPU utilization while scrolling e.g. in PDF files.
